ARIMA

古典密码学中的一些实现加密的算法，用Matlab实现的。(Classical Cryptography to achieve some of the encryption algorithm, using Matlab to achieve.)

这个程序是MATLAB的程序，它能够实现中心频率是4000Hz的带通滤波器的功能，在4000Hz的信号上面加了噪声信号，通过滤波器滤除杂波(This program is MATLAB program that enables the center frequency is 4000Hz band-pass filter function in the 4000Hz signal above the noise signal added, filtered through the clutter filter)

matlab小波包变换实现图像分割，含示例图像，分割结果较好(the matlab wavelet packet transform image segmentation, containing the sample image segmentation result is better)

语音信号处理的一些常用工具及算法，希望对大家有用(Speech signal processing algorithms commonly used tools and, in the hope it would be useful)

二值化算法的经典算法：大津法Matlab源码，有较高的参考价值(Classical binarization algorithm algorithms: Otsu Matlab source code, have a high reference value)

it s really good code for motion estimation in a video on image processing

东南大学信号与系统MATLAB课后作业源码(Southeast University, Signals and Systems MATLAB source Homework)

恢复临时表空间 收回重做日志组的成员 收回丢失指数 重新创建密码文件(Recover temporary tablespaces Recover a redo log group member Recover from a lost index Re-create the password file)

these are two audio features , LPC whith cepstral coefficients this a feature for speech recognition and speaker recognition , and other feature named zcr for calculate the change of the sing ( + or - ) of the signal.
